SML4758A-E3

Vishay Intertech · Zener Diodes · DO-214AC(SMA)

SML4758A-E3 from Vishay Intertech, in a DO-214AC(SMA). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 K passive Cathode, the terminal marked by the cathode band; it goes positive relative to the anode in Zener regulation, and the SML4758A has a nominal VZ of 56 V at IZT1 = 4.5 mA.
2 A passive Anode, the terminal opposite the cathode band; the maximum power dissipation is 1000 mW at TL = 75 °C.
